I would like to show a few examples of various combination printings of Canadian stamps.
In 1968 Canada Post decided to add some colour to their stamps and therefore asked their then current printer
Canadian Bank Note Company, Ottawa to provide more colour capabilities with their presses . They also added
British American Bank Note Company, Ottawa and in 1971
Ashton Potter Ltd, Toronto.
CBNC and BABNC also printed Canadian paper money and had ofcourse experience in engraving but in the beginning were just experimenting with combination presses. Ashton Potter used only offset/lithography.
BABNC combined steel engraving with photogravure as shown by the 2 examples below.
I will show first the plate block with the printers inscription and then a close up of the single for more detail.
Scott # 482 1968
Scott # 494 1969
CBNC decided to go with steel engraving combined with offset/ lithography. See one early example below from 1969
Scott # 501
one from 1998 where you can see they added in the selvage the printing colours used and the letter
P which stands for Peterborough the paper manufacturer.
Scott # 1738
and more recent, the $2 SS from 2005
BABNC (engraving) and CBNC (lithography) produced a joint effort with the next one.
Scott # 655
British American Bank Note and Ashton Potter combined to print the 1972 $1 and $2 definitives.
Scott# 601
Finally an example where the same definitives were reprinted by a different contractor.
CBNC first printed the low values of the 1977 definitives using steel engraving/lithography. See the 4c below.
Scott # 709
Then in 1979 British American Bank Note reprinted them, combining steel engraving with photogravure. Notice the mottled background which is characteristic of photogravure.
Scott# 784
